Embodiment of the present application

[0028] The present application will be described in detail and specifically through specific examples below to better understand the present application, but the following examples do not limit the scope of protection of the present application. Example

[0029] The embodiment discloses a swing type power generation device, which comprises a workbench 1, a power generation assembly 2 and a support assembly 3.

[0030] The workbench 1 adopts an octagon structure. The workbench 1 is internally provided with a containing cavity 11, and the containing cavity 11 is internally provided with liquid 4 for increasing the swing frequency and swing amplitude of the workbench. In the embodiment, the liquid 4 is water, the amount of the liquid 4 accounts for 60% of the volume of the containing cavity 11, and the liquid 4 does not fill the containing cavity 11 and can freely swing in the containing cavity 11.

[0031] The power generation assembly 2 comprises a rotating assembly 21, a transmission assembly 22 and a generator 23. The rotating assembly 21 comprises a transmission rod 211, a connecting rod 212, a pendulum 213 and a slide 214. The transmission rod 211 is arranged at the center position of the slide 214, and the connecting rod 212 is fixedly connected with the transmission rod 211 and the pendulum 213 at two ends, respectively. The slide 214 is a circular slide with the transmission rod 211 as the center.

[0032] When the workbench 1 is tilted and swings under the action of an external force, the pendulum 213 rotates along the slide 214 under the action of gravity and drives the transmission rod 211 to rotate. The transmission rod 211 rotates and further drives the generator 23 to generate electricity through the transmission assembly 22. The bottom of the pendulum 213 is provided with a pulley 215 matched with the slide 214, and the pendulum 213 slides along the slide 214 through the pulley 215. The main function of the slide 214 is to support and fix, which can support the pendulum 213 and limit the pendulum 213 on the slide 214, so as to avoid the off-tracking and other conditions of the pendulum 213 in the running process. The pulley 215 can reduce the friction of the pendulum 213 when rotating and improve the energy conversion efficiency.

[0033] The transmission assembly 22 comprises a gearbox 221, and the gearbox 221 is provided with an input shaft 222 and an output shaft 223, and the input shaft 222 and the output shaft 223 are perpendicular to each other. The input shaft 222 is fixedly connected with the transmission rod 211 at the tail end and rotates synchronously, and the output shaft 223 is parallel to the working surface of the workbench.

[0034] The generator 23 is arranged on the workbench 1. The output shaft 223 is linearly connected with the rotor shaft 231 of the generator 23 through a shaft coupling 224.

[0035] As shown in FIG. 1 and FIG. 3, the generator 23 and the transmission assembly 22 are arranged in the area surrounded by the slide 215. The connecting rod 212 is arranged above the generator 23 and the transmission assembly 22, and the pendulum 213 swings or rotates from the outside of the generator 23 and the transmission assembly 22. The above structure can simplify the connection mode of the generator 23 and the transmission assembly 22 with the workbench 1, and make it more stable and reliable. The above design can effectively increase the length of the connecting rod 212, increase the moment of the pendulum 213 when moving, and improve the power generation effect. At the same time, the above structure can optimize the space utilization on the workbench 1, and make the distribution of the work components on the workbench 1 more reasonable.

[0036] The support assembly 3 includes a support seat 31 and a spring 32, and the two ends of the spring 32 are fixedly connected with the top of the support seat 31 and the bottom of the workbench 1 respectively. The number of the support assembly 3 can be one or more. In the embodiment, the number of the support assembly 3 is 8, which are evenly distributed on the bottom of the workbench 1.

[0037] In the working process of the embodiment, the support seat 31 can be fixed on the ship body. After the ship body tilts and swings under the action of the sea waves, the workbench 1 can also tilt and swing. The pendulum 213 rotates along the slide 214 under the action of gravity and drives the input shaft 222 to rotate, and then drives the rotor of the generator 23 to rotate through the transmission box 221 to generate electricity.

[0038] In the embodiment, a plurality of springs 32 are arranged on the bottom of the workbench 1, and a containing cavity 11 for storing liquid 4 is arranged inside. The arrangement of the spring 32 and the containing cavity 11 can further increase the instability of the workbench 1, increase the swing amplitude and swing frequency of the workbench when swinging, and make the workbench 1 continuously swing under the action of external force, so that the pendulum 213 can continuously slide along the slide 214, thereby achieving the purpose of continuously and efficiently generating electricity. Embodiment

[0039] The embodiment discloses a swing type power generation device.

[0041] The other structures of the embodiment are the same as those of the embodiment 1.

[0042] On the basis of the embodiment 1, the mast and the sail 5 are additionally arranged in the embodiment, so that the external energy can be obtained, the swing effect of the workbench 1 can be further improved by using wind energy, and the swing amplitude and swing frequency of the workbench 1 can be increased. The sea waves and wind energy on the sea surface can be comprehensively utilized, and the power generation efficiency can be improved.

[0043] Meanwhile, the embodiment can swing by wind energy, so the use scenarios of the embodiment are more extensive, and the embodiment can be used not only on the sea surface but also on sites with sufficient wind energy and vibration energy.

[0045] Traditional sea wave energy power generation devices mainly include a pendulum type wave power generation system and a buoyancy pendulum type wave energy power generation device.

The device has a simple structure, is easy to maintain and repair, and is suitable for various marine environments.

[0047] The buoyancy pendulum type wave energy power generation device directly acts on the buoyancy pendulum by waves, converts the up and down movement of the waves into mechanical energy of the buoyancy pendulum, and then converts the mechanical energy into electrical energy. The device can include a three-stage or four-stage energy conversion process, increasing the controllability and stability of energy conversion.

[0048] Traditional wind energy power generation devices usually have a large impeller. The impeller needs rich and stable wind energy resources to drive, and has high requirements for site selection. In addition, the traditional wind energy power generation device occupies a large area, which is not conducive to deployment in cities or areas with limited space. In addition, the manufacturing, transportation and maintenance costs of large impellers are also relatively high, and they also have certain visual and noise effects on the environment.
